Patent GB-2064033-A (GB)
Title: Drawbar Controlled Trailer Braking System
IPC: B60T11/10
Filed: 1980-11-11
Abstract: The invention provides a towed vehicle brake system responsive to overrun forces having a pair of relatively movable draw bar elements 105, 107 and a brake mechanism on the towed vehicle controlled by relative draw bar element movement resulting from an overrun force. The invention uses a pressure regulating valve 115 for sensing the overrun force between the relatively movable draw bar elements to govern the supply of brake power from a power source on the towing vehicle to the brake mechanism on the towed vehicle so as to increase braking effort with an increase in overrun force. The system can cooperate with a towing vehicle brake system by providing that a brake member on the towing vehicle for operating towing vehicle brakes is associated with a device for detecting such operation and a control means actuated by the device is provided for limiting operation of the towed vehicle brake mechanism to such time as the device detects such operation so as to prevent operation of the towed vehicle brake mechanism when an overrun force is present but the brake member is not operated. <IMAGE>

Title: Acid Zinc Electroplating Solutions and Method Utilizing Ethoxylated/Propoxylated Polyhydric Alcohols
IPC: C25D3/22
Filed: 1980-11-14
Abstract: The problem of low "cloud point" and of foaming associated with the conventional grain-refining agents used in aqueous acid zinc electroplating solutions are reduced or avoided by employing as the grain- refining agent a polyhydric alcohol having three or more hydroxyl groups substituted with one or more oxyalkylene groups and which is soluble in the zinc plating solution. The use of these grain-refining agents also permits continuous operation at higher bath temperatures than is presently possible without deterioration or clouding of the plating solutions, and plating at lower temperatures than is presently possible.

Patent GB-2101828-A (GB)
Title: Exchange cabling
Inventor: SOTHCOTT PETER
IPC: H04B10/80
Filed: 1981-07-14
Abstract: In a complex electronic system, such as a telephone exchange, inter- rack cabling is a substantial part of the system's cost. To reduce this cabling, inter rack communication, at least in respect of information, uses beams of free space electro-magnetic radiation. In the present case infra-red beams are preferred because they are not very susceptible to external interference, and also do not cause much interference with other equipment. In some cases care is taken that the beams are directional, while in other cases such as the distribution of clock pulses some measure of non- directionality may be useful.

Abstract: The subsea wellhead system includes a wellhead 24, a housing seat 70 disposed and connected to the wellhead 24, a casing hanger 50 landed and supported by the housing seat 70, a holddown and sealing assembly 180 disposed in the annulus between the wellhead 24 and casing hanger 50, a running tool 200 attached to the casing hanger 50 for lowering the casing hanger 50 into the well and for initially actuating the holddown and sealing assembly 180, and other apparatus for applying hydraulic pressure to further actuate the seal of the holddown and sealing assembly 120. The housing seat 70 and wellhead 24 are connected by a breech block connection 66, 76. The housing seat 70 maintains a full 360 DEG circumferential bearing surface with the casing hanger 50. The holddown and seal assembly 180 includes an upper rotating member 182 threadingly engaging the casing hanger 50 and suspending a lower stationary member 184. The stationary member 184 includes a Z- shaped portion 220 composed of a plurality of frustoconical metal rings connected together by connector links so as to provide a positive connective link throughout the stationary member 184. The annular links form grooves for housing resilient elastomeric members where, upon the compression of the Z-shaped portion of the stationary member, the elastomeric members initially sealingly engage the wellhead and casing hangar so as to form a metal- to-metal primary seal. The seal is actuated initially by the application of torque through a running tool 200 connected to the casing hangar. The seal is further actuated by the application of hydraulic pressure below the blowout preventer whereby a compression set of the seal is achieved which is greater than the working pressure of the well. The rotating member of the holddown and seal assembly follows the further compression of the seal so as to prevent the release of the compression set upon the removal of the hydraulic pressure. <IMAGE>

Title: Off set printing
Inventor: BIRTLES JOHN FREDERICK
IPC: B41F17/34
Filed: 1983-04-22
Abstract: An ink design (2) is silk screened onto an intermediate surface (3) and is then transferred to an article (5) by a deformable pad (4). In order to provide a large difference in the ink affinities of the intermediate surface and pad these are made of silicone rubbers in which different catalysts are used in the curing of the rubbers. Dibutyltindilaurate as catalyst provides an intermediate surface of low ink affinity which can enable 100% transfer of ink from the intermediate surface to the pad when a stannous octoate calysed, condensation cured rubber, or a suitable addition cured rubber, is used for the pad. The screen is heated to a greater temperature than that of the intermediate surface. <IMAGE>
